Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If connection patterns are arranged closely to reduce the number of sensing electrodes, then device complexity is reduced, but electrostatic discharge damage risk increases
Solution Approach 1:
The patent applies local quality by creating different spatial relationships for different connection patterns. Specifically, at least one first connection pattern is positioned at a first distance from a second connection pattern, while another first connection pattern is positioned at a second distance that is greater than the first distance. This non-uniform local arrangement optimizes both circuit compactness and electrostatic discharge protection in different regions of the sensing electrode structure.
Solution Approach 2:
The patent segments the connection patterns into multiple groups with different spatial arrangements. By dividing the connection patterns and assigning different distances to different segments, the design achieves a balance between reducing overall device complexity and maintaining reliability against electrostatic discharge through differentiated local configurations.
2Reliability
If sensing electrodes are spaced apart to prevent electrostatic discharge, then reliability improves, but device complexity increases
Solution Approach 1:
The patent employs parameter changes by varying the distance parameter between different connection patterns. By establishing that at least one first connection pattern is at a first distance from a second connection pattern while another is at a greater second distance, the design dynamically adjusts spatial parameters to achieve optimal electrostatic discharge resistance without uniformly increasing all distances, thereby controlling device complexity.
3Ease of operation
If a hole is defined through the substrate for component access, then ease of operation improves, but electrostatic discharge risk increases
Solution Approach 1:
The patent uses the non-uniform connection pattern arrangement as an intermediary protective structure between the externally accessible hole and the internal electronic components. The differentiated distances of connection patterns from the hole create intermediate zones that can dissipate or redirect electrostatic discharge energy, protecting sensitive components while maintaining ease of operation through the hole.

AI summary
The present disclosure relates to an electronic apparatus. The electronic apparatus includes a base substrate, a first sensing electrode, and a second sensing electrode. A hole is defined through the base substrate. The first sensing electrode includes first sensing patterns and first connection patterns, which are arranged in a first direction. The second sensing electrode includes second sensing patterns and second connection patterns, which are arranged in the first direction. One first connection pattern and one second connection pattern are spaced apart from each other in a second direction with the hole defined therebetween. A first distance in the second direction between the one first connection pattern and the one second connection pattern is greater than a second distance in the second direction between another first connection pattern and another second connection pattern.
